rThis invention relates to paper bags adapted and designed for use as linings for barrels, drums, kegs, boxes and other like shipping containers.

The lnventlon consists of a crinkled pa'-v per bag as an article of manufacture having the features hereinafter pointed out.

The invention seeks to yprovide a crinkled paper lining in the form of a bag having a formed flat bottom which may be produced more rapidly and more than heretofore, and which shall have the capacity to lstretch or expand not only throughout the body of the bag, as heretofore, but shall also have the capacity to stretch or expand around the periphery of the formed fiat bottom.

In the practical art, as heretofore known, a crinkled paper lining for barrels has been used consisting of a tubeopen at'both endsV and without any bottom at all. To take the place of a bottom in that tubular lining, a separate sheet of paper, entirely detached from the tube, was spread over the before the tube was inserted therein. There has also been known in the prior art a crinkled paper barrel lining provided with a round hat bottom. In this latter case, the'bottom was formed by a separate sheet of paper cutI into the form of a circular disk, and then periphery to one end of the tubular body portion. This latter form of bag, because of its round, fiat, seWed-in bottom, has a utilityv peculiar to itself and not possessed by the tubular lining first above mentioned. It was expensive to make, however, because of the requirement to separately cut out the round bottom vpiece and then sew it to the bottom of the body portion. It had also the further objection that it possessed little or no capacity to stretch around the periphery of the bottom owing to the stitches Awhich united the bottomwith the body portion, so that the essential capacity offthe paperfto stretch under strains incident to its use, which was present. in the body of the bag, was not present around the peri hery of the bottom. This lack'of stretcha ility around the periphery of the bottom made the bag liable to rupture when under strain in the locality stated, and such strain occurredk not only in filling the barrel, but also thereafter by the shiftmg of the material within the barrel economically just above referred to,

incident to handling. Such lack of stretchablllty also made .it impractical to stretch or expand the periphery of the flat bottom, as occasion might require, so as to always make it fit snugly into the bottom corner of the barrel formed by its bottom and dy portions. The present invention provides a crinkled paper bag possessing all the advantages of the bag having the fiat sewed-in bottom and having the further advantages 'of greater economy in production and stretchability throughout the periphery of its fiat formed bottom.

Reference is now method illustrated in elusive.

The blank used in 4 carrying out this method is illustrated in Fig.-14 1n the form of a flat bag which may be made by folding the opposite sides 30a and 30b of a sheet of paper along 'the line 31 to bring the opposite margins together along the edge 32. These margins are then fastened together either by stitching or pasting, as indicated at 33 and the unformed bottom of thel flat bag blank is produced by fastening together the doubled over sides of the blank as indicated at 34. This may be done either by pasting, stitching or in any other suitable manner. A blank having the same configurartion and suitable for the present purpose can be made byA having the edge 34 arcuate, the seam 33 arranged one-half way between the edges of the flattened bag, or the edge opposite that denominated 34 can whereupon the bottom of the bag would be along the edge designated 31. blank possesses an unformed formed ilat made` to the bag' and Figs. 1 to 14 inbottom. It does not possess a bottom. For the sake of uniformity in the all the bags are illustrated as from a flat bag blank fashioned in the manner illustrated in Fig. 14.

The flat bag blank 30 is opened out and passeddownwardly over a former 35,.illus trated in dotted lines inv Figs. 1 to 8 in-k clusive. This'former may be made in the form of a round table top. rlhe bag is preferably put on *he former so that the seam 34 in the bottom of the flat bag is directly above the center of the former. The blank is then forced a ainst the former so as to bring the centra portion 34 of the seam 34 against the former. At the same time the drawlngs,

paper .is brought against a portion of the I periphery of the former, forming a crease 59 (shown in Fig. 14). The condition of the bag at this time is illustrated in Figs. 1, 2 and 3, where it will be noted that the material above the former is a continuation of the material of the side walls. lt also appears that the excess end portions or corners 36 and 37 of the blank have been drawn inwardly toward one another a slight distance and the-bottom seam 34 ,is now divided into several sections. T he operator then moves the hands or suitable tools along the seam 34 to about the region indicated by lines 38 and' 39 thereby providing a central zone 40 which is held liat upon the top of the former. The seam 34 now has the configuration shown in Fig. 2, the portion 34a being adjacent the former, other portions 41 and 42 standing' uprightly away from the formerl and the remaining portions 43 and 44 extendingbliquely toward the corners 36 and 37.v

The operator then folds the material along the lines 38 and 39 to the position indicated in Figs. 4, 5 and 6. Thev material is now creased along the lines 45, 46, 47 and 48 and the excess end portions or corners 36 and 37 of the original flat blank are brought closer together. The material between the creases and 46 is now pressed down toward the former and the operator so regulates and controls the pressure that a crease 49 is formed, which extends from the point o f and 46 out to the side 32 of the original blank. A corresponding crease 50 is formed on the yopposite side of the bag. This is shown mostclearly in Fig. 6.

The portions 41 and 42 of the bottom seam 34 have now been Adoubled down and laid against the intermediate portion 34a of this seam, extend upward at a considerable angle. The round bottom of the bag is completed by folding the remaining excess end portions in these projecting corners down to the posi# `tion indicated in Figs. 7 and 8, thereby com-- pleting the formation of infolded free flaps which fall short of the center of the bag bottom. These flaps, which are made from the spread out closed corners of the blank, have a lower side which continues over to the side wall of the bag, while the upper side extends only so vfar -as the folds 38 and 39.

The operator then folds the opposite sides 5l and 51" of the bag, as indicated in Fig. 9, thereby making creases along the lines 52, 52', 53. 53 vand bringing the material cbetween these creases in under the former 35. The. bagl with the formed bottom is withdrawn from the former. the latter mentioned folds being temporarily straightened' out.` The bag may then' be folded to the position indicated 'n Fig. 11, in which the opposite sides 3()a and 30b are brought close together and at an angle to the formed bottom. When this is done, creases 54, 55, 56 and 57 are formed in the material ot the bag. These creases extend from the opposite edges 31 and 32 of theoriginal flat blank toa point quite clbse to the outer end of the creases 45, 46, 47 and 48. rl`he bag is th'en intersection of the creases 45.

while the portions 43 and 44 #ne-24,52@ l ,folded along the line. 58 to the position-indicated in Figs. 12 and 13 in which the formed lat bottom and the remainder-of the 'bag are close together and. in positionv for shipment. The bag has been collapsed into a flat object and thefolds of the formed bottom retained, so that the'bag can be are used in all the figures to indicate these, lcreases and the creases have been indicated .in Figs'l to 12 even though they would not appear in the ordinary making ofthe# bag with the formed flat bottom out of the original flat blank. These creases are iI 1-l dicated Ain the position that they would assume were the previously completed bag unfolded and then refolded, and for this purpose the drawings may be considered'as in addition to the original convertmgnofthezl illustrating such a refolding process blank into a ilat bottom bag.

tom bag illustrated in Figs. 15 and 16. A

blank, suggested for use in connection with the vprocess outlined in Figs. 1 to 14 inclusive,

Y is'spread open and drawn' over a former 35 as before, bringing the bag to a position about like that illustrated in Fig. 2." The operator, instead of carefully folding the,v

simply passes the paper as outlined above, hands or suitable tools inwardly from the opposite edges 60 and having outsi tion as the folds 45, 46, 47 and 48, as previously described. .These outside folds uconverge toward thecorners 36a and 37 which are brought closer together than the corners 36 and 37, and terminate adjacent theline connecting the point 60 and 61.

The excess paper of these Vflaps which lies between Vthe marginal folds will naturally be brought into a plurality of irregularly formed folds, indicated bv the heavier lines converging toward( the point of intersection of the marginal folds. The flaps, like those previously described, are free, aind have lower sides which extend over to the side walls of the bag, and upper sides whichu `extend to transverse folding lines 68 and.

69, corresponding approximately to the lines 38 and 39. While these lines 68 and 69 are shown straight in .the drawing, it is to be understood that they indicatev the general location of the irregular line of fold which tothe position o a 'is held back. which maybe the same as the blank 6l and presses thev excess projecting end portions or closed corners of the blank down toward the former..` -This produces infolded flaps 62 and 63j v de or marginal folds 64, 65,66

and 67 located in somewhat the 45 will be formed when the material is crushed down toward the former. The side seam of the originalqflat blank (corresponding to the .'seam 33 of Fig.- 14) is indicated in Fig: 15

at and 71. It' will be'noted that a portion of this sea-m extends from the periphery of the formed bottom in toward the corner 37a where the bottom seam of the original blank commences.' This bottom seam is in a number of irregular folds whicho extend across the central portion of the bottom between the folding lines 68 and 69 and inside the infolded flaps. v

` In making tlieubag according to thislmethod, a creaseis` formed in the material about the edge ofgthel former 35.l After the operatorihas formed up.v the bottom in the manner above described, the bag is removed from'the former. with `the formed bottom intact in'y such a manner that the bottom is infoldedjas indicated in Fig. 16. This infold- ,ing preferably'extendsy between the points 60 and 61 on a line substantially coincident with the bottomedge; of the bag blank, and may beac'complished by grasping the upper and lower edges 72 and 73 lof the .formed bottom and pullingthem up away from the former, Reference is now made tothe round loot-M while the central part of the formed bottom -The collapsed bag now assumes a flat condition and is then ready for shipment, the folds and formed bottom being retained.`

It is so shownin Figi 16, parts being broken away. `The portion 71-of the side seam of the origiral bag blank extends from the point designated 60 to the end 37 of theV bottom seamf34. This bottom seam extends back from the point 37a tothe corner 68 where the central portion of the bag is doubled upon itself,-this point corresponding to a partjofjthe'folding'v line 6 8.,l The seam 34'then continues across this folded central portion of the bottom'` to thepoir 1t ;f.69 :(corresponding to 68a) whereitis'folded back to the corner 36?. Figs. 17, 18 and 19 illustrate the making' lining in substantially thev same' of abox manner as that in which the Abnag of igs. 1'5

and 16 was made. In this case a rectangular former 80 is used ,which hasa configuration.

conforming tothat of the inside of the bottom `of the box for which the lining is to be made. The former has longer parallel sides 81 and 82n and shorter ends 83 and 84. The flat bag blank of the type above described is drawn over the former so as vto bringthe bottom seam 34 across the center of the former and parallel to the edges 81' and 82.

The operator then creases the material along all, or merely a. portion, of the edges 'lhis -leavesupstanding the excess project-` ing end portions -86 and 87 inthe form of triangular flaps whiclrmust 'now be disposed of. They may be disposed'of in either of 81 and 82 so as to define creases 85 `and 85.

formed flat bottom. with @depending sides two ways. The drawing of the material across the top of the former will naturally bring aboutlines of fold 88 and 89 adjacent the ends 83 and 84 of the former. The upstanding flaps may be folded inwardly so as to bring the cornersA 90 .and 91 down onto the seam 34. In this case, a more or less well defined crease will be formed in the material between the side of the bag and upper surface of `the infolded flaps. The flaps 86 Band 87 may also be disposed bf by turning them. over and ressing them down against the former and ending them away from one another and down alongside the of the lining. In either case, the bag when in this condition has a which it may be fitted into the bottom of a box of corresponding size.

The operator manner similar to the collapsing of the bags shown inFigs. 15 and 16. This is done by bringing the parallel creases 85 and 85 toward one another and disposing of the flaps inside the doubled bottom, or outside it, depending upon which wa*v the flaps were turned. Whenthis is done, the creases 88 and 89 are retained, while the companion 'creases formed in the outside layer of material are straightened out. .This condition is illustrated in Fig. 18. The completely collapsed bag, ready for shipment, is shown in Fig. 19. The flat object has the same Width as the original Hat bag blank from which it was made. Ancillary -creases '92 are formed which extend fromthe sides of the collapsed bag up to the creases 85 and 85. The material 93 included between the airs of creases 92 together with the outside thickness of the flaps 86 and 87, is brought into a couple of free folds tuckedv in in the manner indicated.

When it is desired to open up this bag to form. a lining, it is merely inserted inside the box and pressure supplied to open up the infolded tucked bottom.

The bag illustrated in Figs.v 20 and 21 has a formed bottom similar to that illusltrated in Figs. A17 to 19, and Fig. 2b may be considered as showing the conpletely formed bottom. of the bag of Figs. 17 to 19.

For clearness, the same reference' characters are used-in showing this lining as were lused in describing the lining of Figs. 17 to 19 with the subscript a added, it seeming unnecessary to repeat the descriptive matter. While the bag with the completely formed bottom is still on the former, the sides underneath the edges 8,3` and 84 of the former are tucked in and folded up underneath the former in somewhat the same fashion as indicated in Fig. 9 with respect to a round bottom bag. The bag is then removed from the former and the narrower side walls tucked in, the line of fold being illustrated the then collapses the bagi in a 4 at 95. In doing this, diagonal creases 96 and 97 are formed in the material of the side walls, these creases extending from the corners of the triangular flaps 86 and 87 to meet the middle of the side wall at a point spaced from the folds 88a' and 89a. The bag is then in the position indicated in Fig. 21, in which the creases 85 and 85a are brought together to provide an infolding tuck at the bottom of the bag, the side tucks being collapsed.

In making up these articles from crinkled paper, the blank is generally made by foldlng a -plece'of c'rinkled paper on a line parallel with the crinkles, closing up the edges to form a tube and then closing one end of the tube `to provide a flat bag. The direction of the crinkles is illustrated by the short wavy lines in the drawings, and it is obvious that the bottoms and side walls of bags formed in this manner are extensible in every direction to the limit of stretchability of the paper.

Where the bottoms are sewed in, even though the linings are made, of crinkled paper, the expansion is limited by the stitching. The extensibility of the crinkles adjacent the stitching is not available, whereas in the present invention the crinkles are not restricted in their capacity to stretch .and on account of the freely folded excess end portions, expansion may take place around the entire periphery of the formed flat bottom and at the corners next the head of the barrel. The sewed bottom linings are weakest at the seam, and such inserted bottom cannot stretch in around' its periphery. The present lining'has a bottom which is expansible in all directions, and has no vulnerable seam. It is furthermore much cheaper to make. v

. The creases which are formed in crinkled paper, when the bag is made up in the present manner, are not particularly well defined creases, such as would appear in bags made of plain paper. They are -more or less `rounded. On account of the rounded corners and the extensibility'of the paper, it is obvious that the linings are able to adjust themselves to any irregularity in the box or barrel in which they are placed.
